Revista mexicana de ciencias agrícolas , 2011,
Abstract: agricultural scientists are influenced by several factors when defining the approach to their research. the aim of this paper was to identify demographic, professional and institutional aspects and internal-external influences related to the sustainable, environmental or productivist approach of scientist in aguascalientes, mexico in 2008. the approaches underwent a correlation analysis with 44 influence factors. the sustainable approach had a positive correlation with the specialty, problem-solving with institutional interest, studies on farmers' fields and investigation on farming systems; and a negative correlation with basic research and biotechnology. the environmental approach had a positive correlation with the opinion of the interdisciplinary group in the definition of the problem under investigation. the productivist approach had a positive correlation with specialty, the opinions of users and colleagues in defining the problem, studies on farmers' fields and in the experimental stations, work by technological components and with the researcher's objectivity and a negative correlation with the environmental discipline. the logistic regression model for research with a sustainable approach can be explained by the origin of the researchers, research leaves, type of institution, and source of funding, research on demand of the user and institutional priority, interdisciplinary work, studies on farming systems and by technological components. the environmental model can be explained with research leaves, approval of projects by a technical committee, studies on farmers' fields, interdisciplinary work and studies on farming systems. the productivist model had explicatory variables of the types of institution and work on farming systems.
Enfoques de investigación sostenible, ecologista y productivista: influencias en los científicos(as) Research approaches sustainable, ecological and productivist: influences on scientists

Revista mexicana de ciencias agrícolas , 2011,
Abstract: Los científicos(as) agropecuarios(as) están influenciados(as) por diversos factores para definir su enfoque de investigación. El objetivo de este trabajo fue identificar aspectos demográficos y profesionales, institucionales e influencias internas-externas asociados al enfoque sostenible, ecologista o productivista de los científicos(as) en Aguascalientes, México en 2008. Los enfoques fueron sometidos a un análisis de correlación con 44 factores de influencia. El enfoque sostenible correlacionó positivamente con la especialidad, la solución de problemas de interés institucional, investigación en terrenos de productores e investigación en sistemas de producción y negativamente con investigación básica y biotecnología. El enfoque ecologista correlacionó positivamente con la opinión del grupo interdisciplinario en la definición del problema a investigar. El enfoque productivista correlacionó positivamente con la especialidad, opinión del usuario y colegas en la definición del problema, estudios en terrenos de productores y en la estación experimental, trabajos por componente tecnológico y con la objetividad del investigador(a), y negativamente con la disciplina ecología. El modelo de regresión logística para la investigación con enfoque sostenible se explica por el origen de los investigadores(as), estancias de investigación, tipo de institución, fuente de financiamiento, investigación por demanda del usuario y prioridad institucional, trabajo interdisciplinario, estudios tanto en sistemas de producción como por componente tecnológico. El modelo ecologista se explica por las estancias de investigación, aprobación del proyecto por un comité técnico, investigación en terrenos de productores, trabajo interdisciplinario y estudios en sistemas de producción. El modelo productivista tuvo las variables explicatorias tipo de institución y trabajo en sistemas de producción.

Del incierto trabajo a la precariedad asegurada. tendencias y retos de la ocupación en México
Eduardo Manzo Ramos
El Cotidiano , 2000,
Abstract: Si definimos la precariedad como la insuficiencia de ingreso o la necesidad de laborar jornadas mayores a las normales para percibir ingresos suficientes , tenemos que 87.9% de las nuevas ocupaciones en ese periodo pueden calificarse como precarias y la mitad de los ocupados se encuentra ya en esa condición. El asunto adquiere los niveles de desastre cuando la suficiencia es medida en términos de salarios mínimos y se recuerda que en ese periodo el salario mínimo perdió un cuarto de su valor.
Estudios bíblicos del NT: Panorama histórico e implicancias para la teología sistemática
Fernando Ramos
Teología y vida , 2012,
Abstract: El presente artículo pretende exponer el desarrollo que ha tenido la exégesis del Nuevo Testamento en la historia de los últimos dos milenios. Se constata, en primer lugar, que el aporte más significativo de la exégesis a la teología y a la vida de la Iglesia está en estrecha relación con la unión que el estudio bíblico tenga con la regula fidei. Asimismo, se explicita que el modo de aproximación a los evangelios, de parte de los investigadores, está en íntima relación con los modos de pensar y vivir de los seres humanos en distintos momentos de la historia y con algunas vicisitudes que se verificaron en esos momentos; estas diversas aproximaciones de una u otra manera se relacionan con el quehacer teológico. This article intends to present the development that New Testament exegesis has had in the history of the last two millennia. First, it confirms that the most significant contribution of exegesis to theology and to the life of the Church is closely related to the union between Bible study and the regula fidei. Also, it states that the way researchers approach the Gospels is intimately connected to the ways of thinking and living of human beings at different times in history and with some difficulties that were verified at the time; these various approaches relate in one way or another to the theological task.
NUEVOS AVANCES EN EL ESTUDIO CIENTíFICO DE LA COMPRENSIóN DE TEXTOS
MARMOLEJO-RAMOS,FERNANDO;
Universitas Psychologica , 2007,
Abstract: text comprehension is a psychological activity that has attracted the interest of cognitive science for a long time. nevertheless, just recently, neuroscientific studies have emerged in order to unveil the neural machinery behind this activity. this paper reviews some of the classical and, particularly, current works in cognitive science and new advances in the neuroscience of text comprehension. later on, a potential neurocognitive model for text comprehension based on the core concepts of the cognitive and neuroscientific approaches is presented. this model preserves the predictions made by cognitive models as regards comprehension and the architecture of the new neuropsychological models as regards neurocognitive development. finally, questions for future research in both domains and some general conclusions are offered.

Hierarchy of the Real in Contemporary Performative Mimesis
Luiz Fernando Ramos
Revista Brasileira de Estudos da Presen?a , 2011,
Abstract: It departs from the hypothesis of a hierarchy of real(s), with less and more legitimacy, operating in the evaluation of the contemporary spectacular production. The hyper valuation of a given reality, took as a ready-made an instantly, as a source of liveness in the narrative contemporary processes, documentary or artificial, is discussed and seen as metaphysic, against the imaginary works of performative mimesis, which get to strange and amplify the idea of the real.

A simple method for the detection of outliers
Fernando Marmolejo-Ramos
Electronic Journal of Applied Statistical Analysis , 2009, DOI: 10.1285/i20705948v2n1p67
Abstract: This article presents a simple and efficient method to detect multiple outliers using a modification of the Akaike's Information Criterion. The proposed method is exemplified using various examples and implemented in the statistical package R. The core features of the method are that it depends on simple computations, it does not depend on traditional p values, and it signals the absence of outliers. The proposed procedure is applicable to analyse data in all sciences.
On Image Filtering, Noise and Morphological Size Intensity Diagrams
Vitorino Ramos,Fernando Muge
Computer Science , 2004,
Abstract: In the absence of a pure noise-free image it is hard to define what noise is, in any original noisy image, and as a consequence also where it is, and in what amount. In fact, the definition of noise depends largely on our own aim in the whole image analysis process, and (perhaps more important) in our self-perception of noise. For instance, when we perceive noise as disconnected and small it is normal to use MM-ASF filters to treat it. There is two evidences of this. First, in many instances there is no ideal and pure noise-free image to compare our filtering process (nothing but our self-perception of its pure image); second, and related with this first point, MM transformations that we chose are only based on our self - and perhaps - fuzzy notion. The present proposal combines the results of two MM filtering transformations (FT1, FT2) and makes use of some measures and quantitative relations on their Size/Intensity Diagrams to find the most appropriate noise removal process. Results can also be used for finding the most appropriate stop criteria, and the right sequence of MM operators combination on Alternating Sequential Filters (ASF), if these measures are applied, for instance, on a Genetic Algorithm's target function.
